SPECIFICATION forming part of Letters Patent' Np.,7o o,2'19, dated May 2o, 1 902.

Application filed August Z9, 1901. Serial No.' 73,701." (No model.) l

To all whom, it may concern: Y

Be it known that we, CHARLES B. MOORE, of Newton Center, in the county of Middlesex, and GEORGE B. TOTMAN, of Wollaston, in the county of Norfolk, State of Massachusetts, have invented a certain new anduseful Improvement in Feed-Regulators, of which 'the following is a speciiication, reference being had therein to the accompanying drawing.

This invention relates to improvements in feed-regulators whereby the feeding of fluids may be regulated. The invention as herein described relates particularly to feed-regulators for steam-boilers, whereby the supply of water for the boiler may be automatically controlled.

One object of the invention is to provide a simple and sensitive automatic feed-regulator. A

Another object of the invention is to so construct a feed-regulator for steam-boilers that the controlling mechanism thereof may be directly effected from the watercolumn.

Another object of the invention is to so construct a feed-regulator that upon the falling of the Water in the watercolumn below a predetermined point the inlet-valve will be automatically opened.

The invention consists in the water-column, the tube extending into the Water-column, the float-chamber mounted on said tube and having the elongated stuffing box, and a bucket-float Within said float-chamber and having a rod rigidly secured to said bucket extending through the perforation in the bushing.

The invention still further consists in such other novel features of construction and combination of parts as shall hereinafter be more fully described, and pointed out in the claim.

The drawing representsV a View of a portion of a steam-boiler with a sectional view of the water-column thereof and the improved regulator mounted on the column and connected with a balanced valve in the water-feed pipe.

In the drawing, represents a portion of any ordinary boiler or other device or mechanism adapted to receive a fluid-supply, 6 indicating the fluid-supply pipe, which is controlled by any ordinary balanced valve. In

the present Vinstance-the valven'- stem 7 is shown as furnished with the lever; 8, carrying the balance-weight 9.

Mounted'onfthe boiler'or other receptacle l 5 is ,the watercolumnllO, of any usual construction and connected in the ordinary manner with the boiler or receptacle y5. This column 10 has the ,usual gage-cocksll, 1 2, and

13 andthegage-tube 14, connecting with the interior of the column for determining the height'of water in the boiler. Preferably in the top of the column is formed an opening inwhich Vthelbushing 15 is screwed, and in this bushing isscrewed the tube 16 in the nature of gage-pipe, the lower open end of which extends down into the column 10 to a point approximately opposite thegage-cock 12. On the upper end of the tube 16 is mounted the chamber`l7; furnished with the top 18, secured to such vchamber with a steam-tight joint and having the laterally-extending arm 19. In the center of this top 18 and axially disposed with relation to the tube 16 is an opening in which is secured the bushing 2O in the nature of an elongated guide-tube, having the enlarged shoulder 21 and provided at its outer end with the compression-cap 22 to form a stuffing-box. Through the long perforation in bushing is freely movable the rod or stem 23, having at its upper end slotted ears, as 24, and fixed at its lower end in the `conical weighted bottom 25 of the bucket 26.

On the upwardly-extending portion 19 of the arm 19 is pivoted the lever 27, carrying the adjustable balance-weight 28, this lever being furnished with pivots which are engaged in the slots of the ears, as 24, of the rod or stem 23 at one end and at the other end being connected by the rod-29 with `the lever 8 of the'herepinrshown balanced valve, or said lever 27 may be operatively connected in any desired manner withk anyiother valve adapted to be actuated or controlled by the movement of said lever.

It is obvious that the height of the chamber 17 must be such that the desired move-- ment of the bucket 26 may be effected. It is also understood that any ordinary valve `may be introduced between the column 10 and the chamber 17 when such becomes nec- IOO essary or desirable and that said chamber 17 may be furnished with :t petcock 30.

' The operation of the device is as follows: Vater is introduced into the boiler and enters the Water-column 10 by the usual connections, tlling the column 10 and passing through the tube 16 to ll the chamber 17 and its bucket-float 26. The connections between the rod 23 and the supply-valve are now adjusted in proper relation. Vhen the Water-level in the boiler falls to a, point where the Water-level in the column 10 drops below the end of the tube 16,the water in such tube also falls and a, vacuum is created at the upper part of the chamber 17, the bucket 26 will begin to rise, and the rod or stem 23 will lift this end of the lever, and through the connections the supply-valve willbe partially opened, water will enter the boiler, and the column 0f wetter in the gage pipe or tube 16 will move upward, causing the illing of the chamber 17 and allowing the bucket 26 to drop sufficiently to cause the closing of the supply-valve through the connections there'- with.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- The combination with the column 10, the gage pipe, or tube, 16 extending therein and furnished with the float-chamber 17 ,the cover 18 for said chamber, and the elongated stuifng-box and guide 2O secured in a perforation of such cover, of the bucket 26 having the Weighted bottom 25, the stem 23 rigidly secured in said bottom and working through the stuffing-box 20, and controlling connections for connecting said stem 23 with a, supply-valve.

In testimony whereof we atix our signatures in presence of two witnesses.
